I are developing an encoding application on i.MX6Q Sabre board using Freescale Yocto Project BSP code (imx-3.14.52-1.1.0_ga).
I would like to change rate control (quant param control) of macro-block level.
I think that it is necessary to change the firmware of the VPU. But, there are only a binary file (vpu_fw_imx6q.bin) of the firmware in yocto project.
Can I get the source code of VPU firmware or sample code from somewhere?
